I don't really understand why hating someone by default means you want them dead. Hate is why he beats them to a pulp in the first place. You don't beat someone to within an inch of their life if you don't hate them. Even if you don't kill them.

And I'm a woman, and I'm fine with Batman hitting women if they deserve it. But yeah, the taboo against hitting women means he doesn't go that far. Besides the fact that we require less force to take down and injure anyway....
